The causative lesion of TIO, as shown by MRI to identify the particular location.
1A. A 24-year-old female patient with tumor-induced osteomalacia has a lesion located in the right femoral head. The arrow represents the tumor area. 1B: Causative lesion located in the tibial plateau of a 51-year-old male tumor-induced osteomalacia patient. The white arrow represents the tumor area.

X-ray examination before and after joint arthroplasty in the treatment of tumor-induced osteomalacia patients.
2A: Osteoporosis and the causative lesion in a 52-year-old male TIO patient are shown on X-ray before joint arthroplasty. 2B: The patient underwent joint arthroplasty after one year. Osteoporosis was significantly improved, as shown by X-ray.

Pathological results of the patients.
Histopathological examination revealed that the neoplastic cells were spindled to stellate in shape with elaborate intrinsic microvasculature, infiltrating between bone trabecular (HE, 100x).
